en Healt care Management پژوهشي Original article <strong>Background:</strong> Nowadays, administrative violations are becoming a major problem for health care organizations. Therefore, the present study aimed to determine the type and extent of violations among staff working at a medical sciences university in Iran.<br> <strong>Methods:</strong> This Study was a cross-sectional as well as a descriptive study carried out in 2018.&nbsp; Data were gathered from the administrative violations investigation office of one of the medical sciences universities in Iran. All of the administrative violation records with a final verdict in 2017 were reviewed using the census method. Data entered into the Excel software V.2016, and SPSS₁₆ were analyzed using descriptive statistics.&nbsp;&nbsp;&nbsp;<br> <strong>Results:</strong> The most frequent reasons for committing the violations were personal and family problems (30 %), the prohibition to work by a spouse (11 %), illness (10 %), and intention to immigrate to another country (8 %). Other causes of administrative violations included heavy work shifts and night shifts; a sense of responsibility towards patients of other doctors; a defect in the doctor&#39;s timetable registration system; commuting problems; inadequate payment and benefits; lack of familiarity with workplace laws; delay in the payment of fee-for-service in comparison to doctors; and the decision to continue education.<br> <strong>Conclusion</strong>: Organizations need to develop an effective mechanism to prevent administrative violations and manage them efficiently. If a mechanism is not competently designed to investigate and identify the deviations and threats to organizational health, it can lead to violation of rights within the organizations.
